Masks are greyscale images that can be  applied to a layer.  Masks are used to create special effects with precision and can be used to display or hide parts of an image or fade between layers.  The grey value of a mask determines how much it will cover.  When a mask is completely black it will completely mask the layer, when it is completely white it will leave the layer unmasked and when it is grey the layer will be semi-visible.

Masks are created and edited in a raster greyscale mode, therefor all tools that work on greyscale images will work on masks.

Since a mask is greyscale, you can save it with the image in an alpha channel or as a separate image on your hard disk.  A selection loaded from the alpha channel can be used as a mask and alternately a mask can be used as a selection. 

 

Mask Basics

It is assumed that you have a basic knowledge and use of loading and deleting masks.

There are three ways to create masks in Paint Shop Pro:

Creating a Mask from an Image

  1. Select the layer that you want to add the mask 

  2. Choose>Masks>New>From Image or right click the mask button on the layer palette

  1. Select the image that you wish to create a mask from the source window from the drop down list.  It can be any open image within the workspace

  1. From  "Create mask from" select the value to create the mask:

    • Source Luminance - the luminance value of the pixel color determines the degree of masking.  Lighter colors produce less masking

    • Any non-zero value - there is no graduation to the masking.  Pixels with color are completely masked; pixels without color have no masking.

    • Source Opacity - the opacity of the layer determines the degree of masking

  2. To invert the mask, select>Invert Mask data check box.  Inverting the mask reverses the transparency.  White becomes black, black becomes white, and greys become their mirror values

  3. To apply the mask click OK to close the dialog box

Creating a Mask from a Selection

  1. Create a selection (for more on selections see lesson plan one)

  2. To mask the selection only - choose>Masks>New>Hide Selection or right click the create mask button on the layer palette and choose>hide selection or

  3. To mask everything but the selection - choose>Masks>New>Show Selection or right click the create mask button on the layer palette and choose>show selection

 

Creating a Mask from a Channel

Masks can be created when an image is split into its RGB, HSL or CMYK channels as each channel becomes an greyscale image when split:

  1. Split the image into channels using one of the three channel splitting options from the Colors menu, leaving the images open and minimized

  1. Make the original image the active image

  2. Choose>Masks>New>From Image or right click the create mask button from layer palette and choose>From Image

  3. From the source window, select which channel image you want to use for creating the mask

  1. From the Create Mask from panel, select the Source Opacity option

  2. Select the Invert Mask Data to invert the mask(optional)

  3. To apply the mask click OK to close the dialog box

Tip: To view a mask using a red overlay, choose Masks>View Mask

 

Saving a Mask

Masks can be saved in two ways:

  • Saving a Mask to the Hard Drive

    1. Choose>Masks>Save to Disk

    2. Select the folder where you want to save your mask

    3. In the file name box select a name for the mask.  From the "Save as type" select the .msk format

    4. Click OK to save the mask

 

  • Saving a Mask to an Alpha Channel

    1. Choose>Masks>Save to Alpha Channel.  The name of the image containing the mask will appear in the available documents

    1. In the available Alpha list, double click New Channel or highlight New Channel and click OK

    2. From the New Dialog box type a name for the new mask

    1. Click OK to save the mask

    2. After the mask has been saved it will still appear in the image.  To delete the mask, from the Masks Menu>Choose>Delete and do not merge  it into the layer*

* The mask is still in the image's alpha channel even though it no longer affects the image.
